Sir Alex Ferguson was the butt of Rio Ferdinand's Twitter inspired joke as the
Manchester United defender mocked Sky commentator Ray Wilkins during a press
conference ahead of tonight's Champions League clash against Chelsea.

Ferdinand has repeatedly used the phrase "stay on your feet" on Twitter since Wilkins was ridiculed for his over-use of the phrase while analysing Tottenham's 4-0 defeat against Real Madrid last Tuesday.

And former England defender Ferdinand lived up to his pledge to use the phrase when making fun of Ferguson's grey puffa jacket after the United manager had joked, "You don't like my jacket, do you?"

Ferdinand said: "Not really, no. But if it helps you stay on your feet it's alright."
